Abiotic Factors and Plant Communities Shape the Distribution of Soil Pathogenic Oomycetes in Chinese Grasslands.

ABSTRACT: The outbreaks of emerging phytopathogens constrain socioeconomic development globally and are expected to intensify in the future along with climate change. Oomycetes, a group of fungus-like eukaryotes, include many phytopathogenic species, making it critical to understand the drivers of their diversity and distribution. This work analyzes 972 soil samples from three major grassland types in China and found that soil phosphorus availability drove oomycete richness, while humidity and nitrogen content affected community composition. Pathogenic oomycete abundance is mostly influenced by precipitation, temperature seasonality, and plant species richness. This work creates a distribution atlas of pathogenic oomycete richness and abundance in Chinese grasslands, using space-for-time methods to
